This book presents new data in Applied Activity Theory (AAT) and Systemic-Structural Activity Theory (SSAT), that can be used in the study of human performance. The SSAT is the high-level generality theory that offers standardized principles of the analyses of human activity. These principles can be utilized in theoretical and applied studies. This multi-contributed book offers a selection of works that will provide a holistic picture of the field. The new data can be utilized for the study of extremely complex human-machine and human-computer interaction systems, and for evaluation of efficiency, complexity, and reliability of such systems at the design stage. Features Shows examples of self-regulative models of various cognitive processes Illustrates a method of study of production process in the construction industry Includes topics on learning, training, and management Covers a new method of computer based automated support of decision making under risk and uncertainty Presents a new method of evaluation of probabilistic structure of tasks, and the method of assessing reliability of human performance

Systemic-structural activity theory (SSAT), founded by Gregory Bedny, is a relatively new unified framework for the study of efficiency of human performance, equipment, and software design. This book presents new recently obtained data in the field of SSAT that can be used in the study of efficiency and complexity of human performance. With increased cognitive demands to task performance, psychological methods of study of human activity play an important role. New principles and revised methods for the study of human work are supplemented by practical examples in manufacturing, construction industry, aviation, and human-computer interaction. Features: Presents new SSAT data Offers, for the first time, comparative analysis of studying efficiency and productivity from the perspective of ergonomics, psychology, and economics Includes examples of evaluation of economic efficiency of ergonomic innovations Provides advanced self-regulative models of activity and of all cognitive processes that describe strategies of task performance Introduces a new efficient method of morphological and analytical quantitative analysis Discusses new methods of evaluation of complexity and reliability of highly variable computerized and computer-based tasks Work Activity Studies Within the Framework of Ergonomics, Psychology, and Economics presents a comprehensive unified psychological theory that can be utilized as a general approach to the study of human activity not only for ergonomists and psychologists, but also for economists that study the efficiency of human performance.
